Description

The The invention relates to a connecting element for constructing a detachable, positive connection between two or more components.

For releasably connecting two or more components, each having a bore, usually threaded bolts are used. Also known are movable push bolts, which are retracted starting from a component in corresponding openings of the opposing component. Disadvantageously, a non-positive connection is established by the retraction of such thrust bolts only in the transverse direction to the direction of movement of the thrust bolt. The use of such thrust bolts, for example for sectional doors is off DE 100 37 329 A1 known. It is a Sektionalfalttor, in which an escape door is embedded without threshold. To anchor the likewise foldable door sections with the adjacent door sections, at least starting from the lowermost door section, push bolts are inserted into corresponding openings of the door sections. Disadvantageously, the door sections interrupted by the door sections remain longitudinally impaired in their stability. The lack of a positive connection in all directions is generally present when two components are connected by shear pins of the type described above.

The Task exists against this background in the construction of a Connecting element, which is a positive connection in all directions between two or more components or counters ts manufactures. It should the detachable Connection can be produced by moving individual parts of the connecting element.

To solve the problem, the invention teaches a connecting element, which is characterized in that

• - a bolt ( 1 ) together with a the outside of the bolt ( 1 ) surrounding clamping piece ( 3 ) and one the outside of the clamping piece ( 3 ) surrounding envelope ( 5 ) forms a telescopic unit, wherein
• - the envelope ( 5 ) on the outside with a first component ( 9 ), and
• - the bolt ( 1 ) as well as the clamping piece ( 3 ) telescopically in the in a second component ( 10 ) provided opening ( 7 ) are retractable, and that
• - in the wall of the clamping piece ( 3 ) for receiving movable security elements ( 8th ) in the radial direction pointing and the wall sweeping openings ( 4a ) are provided, and

in the Contrary to the known and integrally constructed thrust bolts forms the bolt of the connecting element according to the invention together with a clamping piece surrounding the bolt and one on the outside of the clamping piece adjacent Hüllstücks one telescopically constructed unit. The connecting element is over the outside of Hüllstücks with connected to one of the components to be connected. The positive and non-positive connec tion is built after the bolt together with a part of the clamping piece in the second component is retracted and under the influence of continued bolt movement movable in the radial direction securing elements in the corresponding Engage depressions of the second component.

Of the Core idea of the invention is that by accordingly shaped depressions on the lateral surface of the bolt the movement controlled in the radial direction movable securing elements becomes. The repression the additional security elements in the radial direction begins after which the clamping piece together retracted with the bolt in the second component and locked there was under the continued Movement of the thrust bolt.

In a preferred embodiment of the invention, one or more axially aligned recesses are provided on the lateral surface of the bolt in that section which comes to lie on the inside of the second component and is surrounded by the clamping piece. The recesses are ramped with the shallow rising side facing in the direction of the component from which the thrust pin moves away during assembly of the connection. After locking the clamping piece in the region of the second component, the thrust pin moves further in the direction of the second component, wherein the additional securing elements increasingly displaced by the ramp-like recesses in the radial outward direction through the openings of the clamping piece in corresponding recesses on the inside of the second component will be. In principle, it is also conceivable that the moving together with the clamping piece in the second component bolt is moved in accordance with adapted shaping of the lateral surface of the bolt for displacing the securing elements in the radial direction after retraction of the clamping piece in the second component in the opposite direction. After completion of the movement of the bolt, the securing elements are under the pressure of the expanding bolt in accordance complementary shaped recesses on the inside of the second component. When the bolt is withdrawn, the openings in the wall of the clamping piece pointing in the radial direction lie above the securing elements located in the recesses of the bolts. When the bolt is extended, the openings pointing in the radial direction in the wall of the clamping piece lie at the same level with the correspondingly complementarily shaped depressions on the inside of the opening in the second component.

In a development of the invention is provided that the movement of the bolt in the direction of the second component by an inside of the first component arranged stop is limited. The stop should be mobile, i. be adjustable, the setting of the Attack is to be made so that in the area of the ramp-like designed Recesses expanding bolts the fuse elements in the largest possible Dimensions in the appropriate for it provided recesses displaced in the second component. During the Structure of a form-fitting Connection between securing elements and the second component increases at the same time acting on the bolt pulling force, as the bolt at the other end is locked by the stop. As a result, the first component "pulled" in the direction of the second component, thereby increasing the connection between improved the components.

Of the described by the aforementioned embodiment Pull effect can be amplified if the bolt is also in the section that after connection the components in the first component remains, one or more axially having aligned recess. Also with these wells the side directed towards the middle of the first component rises like a ramp at. In the retracted state of the locking bolt also come over this Recesses to lie in the radial direction facing openings of the clamping piece. After introduction of the clamping piece together with the locking bolt in the second component abuts the front side of the clamping piece against a corresponding edge in the second component and is on this Way locked while the locking bolt can continue to move due to the telescopic structure by the bolt movement the security elements also in the area of the first component in the radial direction in the openings in the clamping piece Outside repressed and in the correspondingly complementarily shaped depressions on the Inside of the component pressed.

The Movement of the clamping piece in the direction of the second component is positioned by an end face Limit stop. The stop can be from one in the opening of the second component lying peripheral edge exist. alternative or additionally It is conceivable that the movement of the clamping piece and / or the bolt through one provided on the inside of the Hüllstücks Stop is locked.

It is provided that the hollow cylindrical clamping piece on his has a bevelled outer edge facing the second component end face. The beveled outer edge facilitates the introduction of the clamping piece together with the bolt in the second component and prevents with a slight offset between the first and the second component an introduction the clamping piece completely prevented becomes. The bevel However, the front side must be made so that the clamping piece after Introduction to the second component is locked effectively despite the bevel. It is also conceivable that serving for locking edge in the second component complementary to the frontal bevel of shim is shaped.

It is provided that as securing elements balls or cylindrical Pins are used. The balls have the advantage that their Friction is low and they are due to the rotatability on the changed balance of power during forward and backward movement of the bolt. In principle, however, bolts can also be used as securing elements. To produce a possible positive Connection is at least the facing in the radial direction end faces shaped as a hemisphere. To reduce the friction that under the inclusion of the bolt which continues to move after the clamping piece has been locked is generated, it is advantageous, although the inner end of the Locking pin is rounded or he one of the ramp-like rising coat surface having the bolt adapted shape.

by virtue of the spherical shape of the fuse elements produce the fuse elements with increasing repression the balls have a tensile force that increases until the securing elements with its front side form-fitting at the lowest point in the corresponding depressions on the inside abut the two components.

The mechanism for connecting the two components under the influence of the moving latch bolt also depends on the fact that the diameter of the balls is dimensioned so that the balls protrude with retracted bolt over the lateral surface of the locking bolt, but not over the lateral surface of the clamping piece. This ensures that the locking pin in its Rückbewe movement entrains the clamping piece, ie retracts into the first component. This happens because the securing elements protrude beyond the lateral surface of the locking bolt when they rest at the lowest point of the ramp-like depressions and that easily beyond the lateral surface hinausra ing fuse element thus serves as a driver in the return movement of the bolt in the direction of the first component.

It is within the scope of the invention, that the wells for receiving the securing elements on the inside of the second component not are limited to the hemisphere shape, but as circumferential groove-like Well done are. When using balls as security elements it offers that on the inside of the components a circumferential, im Cross-section semicircular Groove is attached. For a circumferential groove or in azimuthaler Direction extended depressions can advantageously the rotation the parts guaranteed across the bolt become. This rotation can be during the use of the connecting element be advantageous in Sektionalfalttoren with escape door.

It is within the scope of the invention that the bolt is a circular or has a polygonal cross-section. The shape of the clamping piece is at least in the area of the inner opening to the outer shape adapted to the bolt. The same applies to the Hüllstück, due to the telescopic Structure as well as the clamping piece a hollow profile is.

The Wall thickness of the clamping piece must be less than the diameter of the balls. Only this is it is possible that the balls with extended bolt over the lateral surface of the Protruding Hüllstücks.

In a preferred embodiment of the connecting element, the wall of the clamping piece at least an axially aligned slot. In this slot engages a driver, for example in the form of a threaded screw is connected in the radial direction with the bolt. It corresponds the length of the slot about the distance to which the fully extended bolt on the likewise protruding into the second component introduced clamping piece.

The Depressions on the lateral surface of the locking bolt can starting from the top of the bolt the same or a different one Have distance. If the wells have a different Distance from the top of the bolt, the designed Attachment of the recesses located on the inside of the components in the context of manufacturing accordingly more expensive. If the wells on the lateral surface of the locking bolt all the same distance from the tip of the bolt, can the recesses on the inside of the device with the advantage The simpler manufacture are also mounted as a circumferential groove.

to symmetrical distribution of dealing with the radial movement of the fuse elements building forces is provided that the recesses on the lateral surface of Bolzens equidistant on the outer circumference of the bolt are distributed.

It It is conceivable that the Hüllstück for easier Replacement of the connecting element detachably with the first component connected is. To make a detachable connection could Hüllstück for example externally have a thread that is complementary to one in the component cut thread.

The inventive connecting element can also installed in pairs next to or above each other become. To facilitate installation, the fasteners in a pairwise arrangement wholly or partly of frame-like elements surrounded, wherein the frame-like elements like an adapter with the first Component are connectable.

Of course It is within the scope of the invention that, given an appropriate length of the Bolzens and the bolt surrounding the clamping piece also more than two components are connectable. It is also possible that to build a non-positive connection between all to be joined components on the inside of each component the movable in the radial direction fuse elements in accordance abut shaped recesses. The frame-like elements are as far as possible on the corresponding component flat on, so that between the connecting element and the component a preferably stable connection possible is. This is especially true when it comes to the component to the door section a boarded in a sectional door escape door acts. Often out thin-walled Aluminum sheet constructed door sections can over the flat at the door sections adjoining frame elements a larger number punctual Connections, such as rivets, with the connector or the Hüllstück connected become.

For the movement the bolt are different mechanical drives in question. Especially suitable are pneumatic and hydraulic drives or electrical Drives such as spindle motors.

The inventive connecting element is suitable itself for use as a locking element for doors to produce a positive between door leaf and door frames. This also includes the installation of the connecting element in a Door lock.

The connecting element is also used in connection with a sectional folding door provided with escape door. The non-positive connection between the door section as the first component and the respective adjacent door section as a second component is particularly important in sectional folding doors, whose bottom door section extends to the floor in the closed state of the door. The lack of a door sill in the area of the escape door is responsible for the fact that the door sections in the area of the escape door are severely destabilized. This especially affects the opening of the gate. Through the use of the connecting element according to the invention this vulnerability is compensated.

The Installation of the connecting element should be done so that at open escape door the end faces of the telescopically guided unit of Hüllstück, clamping piece and locking pin on the narrow side of the door section lie in a single level.

The Connecting element is suitable for adaptation to the In the corner areas of ocean-going containers provided openings for Securing and transporting these ocean-going containers. In the openings in the corner areas of the ocean-going containers they reach for the lifting device of loading cranes belonging Devices. The openings on the underside at the corners vice versa serve to lock the ocean container during transport on a Truck or an egg senbahnwaggon. With the help of the connecting element according to the invention can be between the appropriate devices and the ocean container a non-positive Be created whose advantage is that with increasing engagement of the movable in the radial direction Security elements a form-fitting and especially backlash-free Connection is established. The advantage of having the security elements due to its rounded outer shape build a backlash-free connection and with increasing intervention in the corresponding wells also a pulling effect on the Bolt is created, is under security aspects with particular advantage when stacking ocean-going containers also ships can be used. The play free Anchoring the ocean container comes in heavy seas special importance.

by virtue of the positive fit when using the connecting element between two components standing connection, the connecting element is also suitable for Preparation of a detachable connection between two components, of which at least one rotates. the Use of the connecting element in mechanical engineering, for example in lathes, or in drilling and grinding machines comes therefore a special meaning too.
